PROBLEM
Rotation detonation engines, or RDEs, hold promise in being more efficient than traditional jet engines and other propulsion systems. A drawback is that RDEs experience instability when pressure waves from the detonation travel too fast for their design. This reverses the flow through fuel and oxidizer injectors.
SOLUTION
Purdue University researchers have developed an injection manifold that reduce backflow and instability, which leads to better engine longevity and performance. The injection manifold design, which is still in the conceptual stages, leverages tesla-valve based injectors that can be built through additive manufacturing.
